Lead-Free Bimetal Bearing Bushes CuSn6.5 with Flange and Sleeve are a crucial component in automobile engines, designed to provide a smooth and durable interface between rotating shafts and stationary parts.
The bimetallic construction of these bushings combines the benefits of two different metals, typically copper and tin alloys. The CuSn6.5 material, specifically, is a tin-based bronze alloy that offers excellent corrosion resistance and mechanical properties. The addition of tin enhances the alloy's machinability and wear resistance, making it suitable for high-friction applications like engine bearings.
The flanged design of these bushings provides added stability and support, ensuring they remain securely in place during engine operation. The sleeve, which surrounds the bushing and provides additional structural integrity, is also crucial in maintaining the bushing's position and preventing any misalignment.
The lead-free nature of these bushings is an important environmental consideration, as it helps reduce the use of harmful materials in automobile manufacturing. This not only benefits the environment but also ensures compliance with strict environmental regulations.
Overall, Lead-Free Bimetal Bearing Bushes CuSn6.5 with Flange and Sleeve are a reliable and durable solution for automobile engines, ensuring smooth operation and extended service life.
Viiplus is always focusing on the overseas markets, by satisfying the
ever-increasing demands of modernization of customers. We could
provide products according to the international standards, and
could also provide as per the customers' requests. With stable

lead-free bimetallic bearings is a kind of environmentally friendly
bimetallic bearings, it is a low carbon steel plate as the substrate, the surface of sintered CuSn6.5P0.1 material steel copper alloy products.
products with high fatigue strength and bearing capacity, good sliding
performance, in many occasions, can replace the lead double metal bearing or
copper sleeve.Bimetallic bearing steel material
Because the matrix is stable to low carbon steel material, so the outer diameter of the shaft sleeve processing accuracy has
been guaranteed, and after the product into the hole does not need
screw fixation, relying on interference fit can prevent the
phenomenon of the outer circle.The change of chemical composition
of the inner surface alloy layer can meet the requirements of
different bearing pressure, different operating temperature and
different sliding speed. The oil groove and hole with different structure can meet the requirements of different
refueling methods and prevent the phenomenon of shaft biting when
the friction surface is designed in production.
The product has the advantages of good abrasion resistance.It is especially suitable for medium speed, low speed and high load.By means of special technology, various oil grooves, holes and holes can be made on the friction surface, so as to adapt to different lubrication conditions.Products have been widely used in automobile engine, chassis, motorcycle clutch, gear pump wipe plate and lifting equipment and other fields.
